Tytuł	Carbon Footprint of Beef Cattle in a Conventional Production System: a Case Study of a Large-Area Farming Enterprise in the Wielkopolska Region
Title	Carbon Footprint of Beef Cattle in a Conventional Production System: a Case Study of a Large-Area Farming Enterprise in the Wielkopolska Region
Słowa kluczowe	carbon footprint, beef production, emission of greenhouse gases, life cycle assessment, agriculture
Key words	carbon footprint, beef production, emission of greenhouse gases, life cycle assessment, agriculture
Abstrakt	Animal production is a significant source of greenhouse gas (GHG) emissions. One of the major challenges in sustainable management is to mitigate the effects of climate change by reducing GHG emissions. The diversity of animal production systems and accompanying diversification of technological processes, mean that specific production effects can be obtained at different levels of GHG emissions. The aim of the study was to determine the carbon footprint (CF) of beef cattle grown in a conventional system (i.e. indoor confinement). The research was carried out on the beef cattle farm belonging to a large-area enterprise, Długie Stare Ltd. The beef cattle production system consisted of the following subsystems: a basic breeding herd (consisting of suckler cows, replacement heifers and calves up to 6.5 months), breeding heifers, breeding bulls and fattening bulls. The method of life cycle analysis (LCA) in the stages from "cradle-to-farmgate" was used to assess the GHG emissions associated with the production of beef cattle. The average CF in the entire beef cattle production system was 25.43 kg of CO2 kg-1 of live weight of marketed cattle, while in the individual subsystems of basic breeding herd, breeding heifers, breeding bulls and fattening bulls, the CF (after GHG allocation) was: 11.0 kg CO2 eq., 34.30 kg CO2 eq., 27.32 and 25.40 kg CO2 eq., respectively. GHG emissions associated with young calves staying in the cow-calf pairs until weaning (in the period from 0-6.5 months), had a decisive influence on the final CF in each of the subsystems of beef cattle production. The second important factor directly affecting the CF was GHG emissions related to methane (CH4) enteric fermentation and manure management. Knowledge of factors affecting the CF structure allows better identification of critical areas in production processes with high GHG emission potential. Information on the CF of beef cattle and beef meat responds to a wider societal demand for the ecological characteristics of market products, which ultimately contributes to improving their market competitiveness.

Tytuł	Produkcja wołowiny w Polsce oraz czynniki determinujące jej opłacalność
Title	BEEF PRODUCTION AND DETERMINANTS ITS PROFITABILITY IN POLAND
Słowa kluczowe	żywiec wołowy, koszty, opłacalność produkcji, zużycie pasz
Key words	beef cattle, costs, profitability of production, feed consumption
Abstrakt	Celem badań była ocena wyników ekonomicznych produkcji żywca wołowego oraz identyfikacja głównych czynników determinujących jej opłacalność. Wyniki produkcji żywca analizowano w trzech grupach gospodarstw, wydzielonych według kwartyli nadwyżki bezpośredniej, tj. w gospodarstwach najlepszych, średnich i najsłabszych. Analizie poddano średnie trzyletnie. Głównym czynnikiem różnicującym efekty ekonomiczne produkcji żywca wołowego były poniesione koszty, wpływ ceny sprzedaży był mniejszy. Decydujący wpływ miały koszty bezpośrednie, które w kolejnych grupach gospodarstw sukcesywnie rosły: w średnich gospodarstwach były wyższe niż w najlepszych o 40,2%, a w najsłabszych – o 82,0%. Wysokość kosztów bezpośrednich była determinowana głównie przez koszt wymiany stada, wpływ miał także koszt pasz. Produkcja żywca wołowego ekonomicznie efektywna była tylko w gospodarstwach najlepszych, wskaźnik opłacalności wynosił 111,9%, natomiast w średnich i najsłabszych koszty produkcji zostały pokryte częściowo, odpowiednio w 88,8 i 72,4%.
Abstract	The main objective of the study was to evaluate the economic performance and efficiency of bovine animals production and identify the main determinants of such production profitability. The results of the study were analyzed in three groups of farms divided by quartiles of gross margin, i.e. in the best, middle and weakest. The results were analyzed as average in three years. The main factor differentiating the economic effects from the production of beef cattle was the costs incurred, the impact of the sale price was lower. The decisive impact was direct costs, which in successive groups of farms increased, with regard to the best of farms in the medium ones were higher by 40.2% and the weakest ones – by 82.0%. The level of direct costs was determined mainly by the exchange cost of the herd and also by the cost of feed. Beef cattle production was economically effectiveness only in the best farms, the profitability index was 111.9%, while in the medium and weakest group of farms at 88.8 and 72.4% respectively.

Abstract	The meat sector in Poland is the biggest one in the Polish food economy. A foremost placein the red meat branch, after pork production, occupies the beef production. The paper presents ananalysis of the cattle production in Poland on the background of other European Union countries in2005. Relative concentration was used for the estimation of the degree of irregularity of stock,production and slaughter of cattle distribution among the European Union countries. The short-termpoint and interval forecasts of stock, production and slaughter of cattle in Poland in 2006-2008 wereprepared
